Endsor gained valuable experience before appearing on the show by appearing at COLIN 2005 where we won 2 games out of 6, facing mainly people who had already been contestants on the show. He won his first televised game with an impressive score of 102, before losing his second game by just a single point in a low scoring game.
Endsor attended COLIN again in 2006.
He is expected to return to the show 15 years after his debut, in Series 82
